# POST /v1/predict/{} stops working

Calls to POST /v1/predict/* on Ultralytics stopped working on July 31, 2026.

On July 31, 2026, Ultralytics shut down its HUB service. Calls to POST /v1/predict/* fail since that date. The change took effect following the managed HUB-to-Platform migration completed during Q2 2026.

## What to use instead

Use the Ultralytics Platform REST API at platform.ultralytics.com/api with a Platform API key instead. Legacy HUB APIs and keys no longer work.
